Lake Surface Sediment Transect from northern Alaska - Leaf wax biomarker (n-alkane and n-acid) indices and hydrogen isotope ratios, 2011-2015

The hydrogen isotope ratio of leaf waxes is an increasingly utilized paleoclimate proxy used to reconstruct past hydroclimate variations. Continued calibration work on this proxy is needed, particularly in the Arctic. One calibration approach is to compare spatial patterns in hydrogen isotope (D/H) ratios of precipitation with those of leaf waxes found in lake surface sediment. This dataset includes biomarker data from lake surface sediments collected from the Circumarctic Lakes Observation Network (CALON) and Toolik Long-Term Ecological Research (LTER) station study lakes between 2011 and 2015. Specifically, the dataset contains leaf wax (n-alkane and n-acid) distribution information and hydrogen isotope ratios from 9 lakes located on the North Slope of Alaska.

叶片蜡质的氢同位素比值是一种愈发广泛应用的古气候代用指标，可用于重建历史水文气候变化。该代用指标仍需开展持续的校准工作，在北极地区尤为必要。其中一种校准方法为，将降水的氢同位素（D/H）比值空间分布特征，与湖泊表层沉积物中赋存的叶蜡氢同位素比值空间分布特征进行对比。本数据集包含2011至2015年间，从环北极湖泊观测网络（Circumarctic Lakes Observation Network, CALON）以及图利克长期生态研究站（Long-Term Ecological Research, LTER）的研究湖泊中采集的湖泊表层沉积物生物标志物数据。具体而言，本数据集涵盖阿拉斯加北坡9处湖泊的叶蜡（正构烷烃与正构脂肪酸）分布信息，以及对应的氢同位素比值数据。
